[0001] This application claims the priority of Chinese Patent
Application No. CN201811467475.6, filed on Dec. 3, 2018, the entire
contents of all of which are incorporated herein by reference.
FIELD OF THE DISCLOSURE
[0002] The present disclosure generally relates to the display
technology and, more particularly, relates to a display panel and a
display device thereof.
BACKGROUND
[0003] As electronic technology advances, manufacturing technology
of display panels is continuing to mature. Existing display panels
mainly include liquid crystal display panels, organic
light-emitting display panels, and electronic-paper display panels,
etc. To increase the screen size and enhance the appearance of the
display device, increasing the screen-to-body ration gradually
becomes a development trend.
[0004] Existing display devices, such as displays, televisions,
mobile phones, tablets, etc., often have generally regular
rectangular screens. With continuous development of display
technology and diversified user demands on the of display devices,
simple rectangular display devices may not meet the consumer
desires. Therefore, various shapes of display devices have emerged.
In the existing technologies, the display device is often designed
to have a shape other than a regular rectangle, and such a display
device is named as an irregular-shaped display device. The
irregular-shaped display devices are able to diversify the screen
of the display devices, thereby being applied to various
products.
[0005] In addition, based on the structural design of the full
screen, a notch is required to be disposed at the irregular-shaped
display panel to mount a camera, an earpiece, a sensor, and the
like. However, the display performance of the irregular-shaped
display panel with the notch is not well, and a split screen is
likely to occur. Accordingly, the uniformity of the display
performance is poor, which degrades the display performance of the
display panel.
[0006] The disclosed display panel and display device thereof are
directed to solve one or more problems set forth above and other
problems.

edge other than the at least one sub-edge extend in the column
direction. The non-display area includes a first sub-area disposed
adjacent to the at least one sub-edge. The plurality of data lines
include at least one irregular-shaped data line, and the at least
one irregular-shaped data line includes a winding portion disposed
at the first sub-area. The first sub-area includes a compensation
electrode, and in a direction perpendicular to the display panel,
the compensation electrode is at least partially overlapped with
the winding portion.
[0008] Another aspect of the present disclosure provides a display
device. The display device comprises a display panel. The display
panel comprises a display area and a non-display area surrounding
the display area. The display area includes a plurality of gate
lines extending in a row direction, a plurality of data lines
extending in a column direction, and an irregular-shaped edge,
wherein the irregular-shaped edge includes at least one sub-edge
which is recessed towards an inside of the display area to form a
notch, and edges of the irregular-shaped edge other than the at
least one sub-edge extend in the column direction. The non-display
area includes a first sub-area disposed adjacent to the at least
one sub-edge. The plurality of data lines include at least one
irregular-shaped data line, and the at least one irregular-shaped
data line includes a winding portion disposed at the first

DETAILED DESCRIPTION
[0025] Reference will now be made in detail to exemplary
embodiments of the disclosure, which may be illustrated in the
accompanying drawings. Hereinafter, embodiments consistent with the
disclosure will be described with reference to drawings. Wherever
possible, the same reference numbers will be used throughout the
drawings to refer to the same or like parts. It may be apparent
that the described embodiments may be some but not all of the
embodiments of the present disclosure. Based on the disclosed
embodiments, persons of ordinary skill in the art may derive other
embodiments consistent with the present disclosure, all of which
may be within the scope of the present disclosure. Further, in the
present disclosure, the disclosed embodiments and the features of
the disclosed embodiments may be combined under conditions without
conflicts.
[0026] As discussed in the background, when a notch is disposed at
the display panel, a split screen is likely to occur. FIG. 1
illustrates a schematic top view of an existing display panel. As
shown in FIG. 1, the display panel includes a display area 01 and a
peripheral area 02. The display area 01 includes a plurality of
gate lines 03 and a plurality of data lines 04. The display panel
is provided with a notch 05, and an electronic component such as a
camera is disposed at the notch 05. Because the display panel is
provided with the notch 05, a portion of first data lines 041 have
to be wound or routed from the peripheral area 02 to bypass the
notch 05. The data lines other than the first data lines are second
data lines 042 which do not have to be wound from the peripheral
area 02 to bypass the notch 05.
[0027] The display area 01 is provided with a common electrode (not
drawn) for realizing the display function while the peripheral area
02 not. The coupling capacitance of the first data line 041 and the
common electrode is different from the coupling capacitance of the
second data line 042 and the common electrode and, thus, the load
of the first data line 041 is different from the load of the second
data line 042, which causes a longitudinal split-screen of the
display area 01 and, thus, the non-uniform display effects.
[0028] To solve one or more problems set forth above and other
problems, the present disclosure provides a display panel and a
display device thereof.
[0029] FIG. 2 illustrates a schematic top view of an exemplary
display panel consistent with the disclosed embodiments. As shown
in FIG. 2, the display panel may include a display area AA and a
non-display area NA surrounding the display area AA. The display
area AA may include a plurality of gate lines GL, a plurality of
data lines DL, and an irregular-shaped edge 10. The gate lines GL
may extend in a row direction X, and the data lines DL may extend
in a column direction Y. The irregular-shaped edge 10 may include
at least one sub-edge 11 which is recessed towards the inside of
the display area AA to form a notch Q. The edges of the
irregular-shaped edge 10 other than the sub-edge 11 may extend in
the column direction Y.
[0030] The non-display area NA may include a first sub-area 101
disposed adjacent to the sub-edge 11. The plurality of data lines
DL may include at least one irregular-shaped data line DLA, and the
irregular-shaped data line DLA may include a winding portion 20
disposed at the first sub-area 101. The first sub-area 101 may
include a compensation electrode 21, and the compensation electrode
21 and the winding portion 20 may at least partially overlap with
each other in a direction perpendicular to the display panel.
[0031] In the disclosed embodiments, the display area AA may
include the irregular-shaped edge 10. Although the entire
irregular-shaped edge 10 does not have a straight segment shape
(e.g., the irregular-shaped edge 10 is a curved line) and includes
the sub-edge 11 recessed towards the inside of the display area AA,
the portion of the irregular-shaped edge 10 other than the sub-edge
11 may have a straight segment shape extending in the column
direction Y. Also, because the sub-edge 11 is often substantially
short, the influence of the sub-edge 11 on the overall extension
direction of the irregular-shaped edge 10 may be small. Therefore,
the general extending direction of the irregular-shaped edge 10 may
be substantially the same as the extending direction of the data
line DL, i.e., both extending in the column direction Y.
[0032] In the disclosed embodiments, the display area AA of the
display panel may be irregular-shaped, and the display area AA may
include the notch Q. Correspondingly, the display panel may form a
groove R at the position of the notch Q. When the display panel is
applied to the display device, the notch Q and the groove R may
bypass or give way to the space where an electronic component such
as a camera is disposed, which may realize the full screen.
[0033] Because the display area AA includes the notch Q, at least
one data line may be desired to be routed from the first sub-area
101, i.e., the irregular-shaped data line DLA. In one embodiment,
the data lines except the irregular-shaped data line DLA may be
regular data lines DLB. It should be noted that, for illustrative
purposes, FIG. 2 shows three irregular-shaped data lines DLA. In
practical applications, the number of the irregular-shaped data
lines DLA may be one, two, four, or five or more, which is not
limited by the present disclosure.
[0034] The irregular-shaped data line DLA may extend through the
non-display area NA. The non-display area NA may include a first
sub-area 101, and the first sub-area 101 and the display area AA
may be separated by a sub-edge 11. A portion of the
irregular-shaped data line DLA where the portion is disposed at the
first sub-area 101 may be the winding portion 20. The first
sub-area 101 may include at least one winding portion 20.
[0035] In the disclosed embodiments, the compensation electrode 21
may be disposed at the first sub-area 101, and the compensation
electrode 21 and the winding portion 20 may at least partially
overlap with each other in a direction perpendicular to the display
panel. FIG. 2 illustrates a view obtained by observing the display
panel in the direction perpendicular to the display panel and,
thus, the direction perpendicular to the display panel is a
direction perpendicular to the plane of FIG. 2. In the direction
perpendicular to the display panel, the compensation electrode 21
may overlap with a portion of the winding portion 20 or may
completely cover the winding portion 20. For illustrate purposes,
FIG. 2 shows the compensation electrode 21 partially overlaps with
the winding portion 20 in the direction perpendicular to the
display panel.
[0036] In the disclosed embodiments, the compensation electrode 21
may be disposed at the first sub-area 101, and the compensation
electrode 21 and the winding portion 20 may be overlapped to form a
coupling capacitance, thereby increasing the load of the
irregular-shaped data line DLA. Accordingly, the load difference
between the irregular-shaped data line DLA and the regular data
line DLB may be reduced, the split-screen of the display panel may
be suppressed.
[0037] The area of the compensation electrode 21 may be designed
according to the actual requirements of the display panel. For
example, when the load difference between the irregular-shaped data
line DLA and the regular data line DLB is large, the area of the
compensation electrode 21 may be appropriately increased, thereby
increasing the coupling capacitance between the compensation
electrode 21 and the irregular-shaped data line DLA. When the load
difference between the irregular-shaped data line DLA and the
regular data line DLB is small, the area of the compensation
electrode 21 may be appropriately reduced, thereby preventing the
coupling capacitance between the compensation electrode 21 and the
irregular-shaped data line DLA from being excessive.
[0038] Moreover, the distance between the compensation electrode 21
and the winding portion 20 in the direction perpendicular to the
display panel may also be designed according to actual needs. For
example, when the load difference between the irregular-shaped data
line DLA and the regular data line DLB is large, the distance
between the compensation electrode 21 and the winding portion 20 in
the direction perpendicular to the display panel may be
appropriately reduced, thereby increasing the coupling capacitance
between the compensation electrode 21 and the irregular-shaped data
line DLA. When the load difference between the irregular-shaped
data line DLA and the regular data line DLB is small, the distance
between the compensation electrode 21 and the winding portion 20 in
the direction perpendicular to the display panel may be
appropriately increased, thereby preventing the coupling
capacitance between the compensation electrode 21 and the
irregular-shaped data line DLA from being excessive.
[0039] That is, both the area of the compensating electrode 21 and
the distance between the compensating electrode 21 and the winding
portion 20 in the direction perpendicular to the display panel may
be designed according to various application scenarios, which is
not limited by the present disclosure.
[0040] In the disclosed embodiments, the display area AA may have
an irregular shape with the notch Q, at least one data line may be
desired to be routed from the first sub-area 101, i.e., the
irregular-shaped data line DLA. A portion of the irregular-shaped
data line DLA in the first sub-area 101 may be the winding portion
20. The compensation electrode 21 may be disposed at the first
sub-area 101, and the compensation electrode 21 and the winding
portion 20 may be overlapped to form a coupling capacitance,
thereby increasing the load of the irregular-shaped data line DLA.
Compared to the existing display panel, in the disclosed display
panel, the load difference between the irregular-shaped data line
DLA and the regular data line DLB may be reduced, such that the
split-screen of the display panel may be suppressed, the uniformity
of the display performance may be improved, and the display
performance may be enhanced.
[0041] Referring to FIG. 2, the display panel may include a groove
R that penetrates the display panel along the thickness direction
of the display panel. The groove R and the first sub-area 101 may
be disposed adjacent to each other in the row direction X. It
should be noted that the thickness direction of the display panel
is the direction perpendicular to the plane of FIG. 2. In the
disclosed embodiments, the notch Q and the groove R may be disposed
correspondingly. When the display panel is applied to the display
device, the groove R may be able to bypass the space for
accommodating an electronic component, which may realize the
display performance of the full screen.
[0042] FIG. 3 illustrates a schematic top view of another exemplary
display panel consistent with the disclosed embodiments. The
similarities between FIG. 3 and FIG. 2 are not repeated here, while
certain differences may be explained. As shown in FIG. 3, the
plurality of gate lines GL include at least one first gate line
GL1, and the first gate line GL1 may include an extending portion
GLA disposed at the first sub-area 101. The compensation electrode
21 and the extending portion GLA may overlap in the direction
perpendicular to the display panel.
[0043] In the disclosed embodiments, because the display area AA
has the notch Q, at least one gate line may have to be routed from
the first sub-area 101, i.e., the first gate line GL1. In some
embodiments, the gate lines other than the first gate line GL1 may
be regular gate lines GL2. The first gate line GL1 may extend
through the first sub-area 101 and may include the extension GLA
disposed at the first sub-area 101. The regular gate lines GL2 may
be disposed outside the first sub-area 101.
[0044] Because the display area AA has the notch Q, the length of
the first gate line GL1 at the display area AA may be smaller than
the length of the regular gate line GL2 at the display area AA. The
compensation electrode 21 may overlap with the extending portion
GLA to form a coupling capacitor, which may increase the load of
the first gate line GL1, reduce the load difference between the
first gate line GL1 and the regular gate line GL2. Thus, the
uniformity of the display performance may be improved, and the
display performance may be enhanced.
[0045] It should be noted that, for illustrative purposes, FIG. 3
shows seven first gate lines GL1. In practical applications, the
number of the first gate lines GL1 may be one, two, three, four,
five, six, eight or more, which is not limited by the present
disclosure.
[0046] Referring to FIG. 3, the extending portion GLA and the
winding portion 20 overlap in a direction perpendicular to the
display panel.
[0047] In the display area AA, the gate lines may be intersecting
and electrically insulated from the data lines, and the gate lines
and the data lines may form coupling capacitance at the
intersecting positions. In the disclosed embodiments, a plurality
of extending portions GLA may be intersecting and electrically
insulated from a plurality of winding portions 20, such that the
extending portion GLA and the winding portion 20 may form coupling
capacitance at the intersections, which may further reduce the load
difference between the irregular-shaped data line DLA and the
regular data line DLB and the load difference between the first
gate line GL1 and the regular gate line GL2. Accordingly, the
uniformity of the display performance may be improved, and the
display performance may be enhanced.
[0048] FIG. 4 illustrates a schematic top view of another exemplary
display panel consistent with the disclosed embodiments. The
similarities between FIG. 4 and FIG. 2 are not repeated here, while
certain differences may be explained. As shown in FIG. 4, the
display area AA may include a common electrode CI, and the
compensation electrode 21 and the common electrode CI may be
disposed at the same layer and electrically connected to each
other. In one embodiment, the compensation electrode 21 and the
common electrode CI may be integrally formed. In the process of
manufacturing the display panel, the compensation electrode 21 and
the common electrode CI may be simultaneously formed by patterning
the same conductive layer.
[0049] In the disclosed embodiments, the compensation electrode 21
and the common electrode CI may be disposed at the same layer, such
that the compensation electrode 21 may be fabricated without
introducing an additional film layer, which may reduce the
manufacturing process and the cost of the display panel. Further,
the compensation electrode 21 and the common electrode CI may be
electrically connected to each other and, thus, the electric
potential of the compensation electrode 21 may be the same as the
electric potential of the common electrode CI. Thus, an additional
electric signal may not be desired to supply to the compensation
electrode 21, and the number of signals of the display panel may be
simplified.
[0050] In the disclosed embodiments, the display panel may be a
plasma display panel, a field emission display panel, a
light-emitting display panel, an organic light-emitting display
panel, a liquid crystal display (LCD) panel, a quantum dots (QDs)
display panel, an electrophoretic display panel, etc. Further, the
display panel may include any appropriate type of display panels
which are not limited by the present disclosure. In one embodiment,
the display panel may be a liquid crystal display (LCD) panel, and
pixel electrodes (not drawn) may be disposed at the display area
AA. Through respectively applying appropriate voltages to the
common electrode and the pixel electrode, an electric field may be
formed therebetween for controlling the reorientation of the liquid
crystal molecules, thereby realizing a display function.
[0051] FIG. 5 illustrates a schematic top view of another exemplary
display panel consistent with the disclosed embodiments, and FIG. 6
illustrates an exemplary schematic cross-sectional view of the
display panel in FIG. 5 consistent with the disclosed embodiments.
The similarities between FIGS. 5-6 and FIG. 2 are not repeated
here, while certain differences may be explained.
[0052] As shown in FIGS. 5-6, the display area AA may include a
plurality of touch control electrodes TP and a plurality of touch
control lines TPL. The touch control lines TPL and the touch
control electrodes TP may be electrically connected. The gate line
GL, the data line DL, and the touch control line TPL may be
respectively disposed at different film layers.
[0053] In the disclosed embodiments, the display panel may have a
touch control function. In particular, the touch control electrodes
TP disposed at the display area AA may be arranged in multiple rows
and columns. The touch control electrode TP may form ground
capacitance with the ground as basic capacitance for detecting the
touch. When a touch control occurs on the display panel, the
coupling capacitance between the finger and the touch control
electrode TP may change the basic capacitance. By detecting the
amount of change in the basic capacitance of the plurality of touch
control electrodes, the touch control electrodes that are in the
touch control operation may be detected, thereby determining the
position of the touch control operation at the display panel.
[0054] In one embodiment, the plurality of touch control electrodes
TP may be multiplexed as a common electrode, and the operation
stage of the display panel may be divided into a display phase and
a touch control phase. In the display phase, the touch control
electrode TP may receive a common voltage signal, which is often a
constant voltage signal for realizing a display function. During
the touch control phase, the touch control electrode TP may receive
a touch control signal, which is often a pulse signal for detecting
the touch control operation.
[0055] The display panel may be further provided with a plurality
of touch control lines TPL for transmitting electrical signals to
the touch control electrodes TP electrically connected thereto. The
touch control line TPL and the touch control electrode TP may be
electrically connected by a through-hole K. The gate line GL, the
data line DL, and the touch control line TPL may be respectively
disposed at different film layers, for example, the gate line GL
may be disposed at a first metal layer, the data line DL may be
disposed at a second metal layer, and the touch control line TPL
may be disposed at a third metal layer. In one embodiment, the
display panel may include a base substrate 00.
[0056] FIG. 7 illustrates another exemplary schematic
cross-sectional view of the display panel in FIG. 5 consistent with
the disclosed embodiments. The similarities between FIG. 7 and FIG.
6 are not repeated here, while certain differences may be
explained.
[0057] As shown in FIG. 5 and FIG. 7, the compensation electrode 21
and the touch control electrode TP may be disposed at the same
layer. In one embodiment, the compensation electrode 21 and the
touch control electrode TP may be electrically insulated from each
other, and receive different electrical signals respectively.
Because the touch control signal is often a pulse signal and the
electrical signal at the touch control electrode TP is affected by
the touch control operation, the electrical signal at the touch
control electrode TP may be not constant. When the compensation
electrode 21 and the touch control electrode TP are electrically
connected, the electrical signal at the compensation electrode 21
may be caused to be no longer constant, introducing interference to
the electrical signal at the irregular-shaped data line DLA. In
view of this, in the disclosed embodiments, the compensation
electrode 21 and the touch control electrode TP may be configured
to be electrically insulated from each other, such that the
interference may be no longer introduced to the electrical signal
at the irregular-shaped data line DLA.
[0058] Further, the compensation electrode 21 may be fabricated
without introducing an additional film layer, thereby reducing the
process and cost of the display panel.
[0059] FIG. 8 illustrates another exemplary schematic
cross-sectional view of the display panel in FIG. 5 consistent with
the disclosed embodiments. The similarities between FIG. 7 and FIG.
8 are not repeated here, while certain differences may be
explained.
[0060] As shown in FIG. 5 and FIG. 8, the compensation electrode 21
and the touch control line TPL may be disposed at the same layer.
The compensation electrode 21 may be fabricated without introducing
an additional film layer, thereby reducing the process and cost of
the display panel.
[0061] FIG. 9 illustrates another exemplary schematic
cross-sectional view of the display panel in FIG. 5 consistent with
the disclosed embodiments. The similarities between FIG. 9 and FIG.
8 are not repeated here, while certain differences may be
explained.
[0062] As shown in FIG. 5 and FIG. 9, the touch control electrodes
TP may be multiplexed as a common electrode CI. The display panel
may further include a compensation signal line 22, which is
electrically connected to the compensation electrode 21. The
compensation signal line 22 and the touch control line TPL may be
disposed at the same layer.
[0063] The touch control electrodes TP may be multiplexed through
time sharing. During the touch control phase of the display panel,
the touch control electrodes TP may be used to detect touch control
operations, and during the display phase of the display panel, the
touch control electrodes TP may be used to realize display
function.
[0064] The compensation signal line 22 that transmits an electrical
signal to the compensation electrode 21 may be disposed at the
display panel. The compensation electrode 21 and the touch control
electrode TP may be electrically insulated from each other, and
receive different electrical signals respectively. The touch
control line TPL may transmit an electrical signal to the touch
control electrode TP, and the compensation signal line 22 may
transmit an electrical signal to the compensation electrode 21.
[0065] Because the first sub-area 101 is disposed with both the
data line trace and gate line trace, to prevent the short circuit
caused by the intersection of the compensation signal line 22 and
the data line trace or the intersection of the compensation signal
line 22 and the gate line trace, the compensation signal line 22
may be disposed at the same film layer as the touch control line
TPL. In the manufacturing process of the display panel, the touch
control line TPL and the compensation signal line 22 may be
simultaneously formed by patterning the same metal layer, reducing
the manufacturing process and the cost of the display panel.
[0066] For illustrative purposes, FIG. 9 shows the compensation
layer 21 and the touch control electrode TP are disposed at the
same layer. In another embodiment, the compensation electrode 21
may be disposed at other film layers, which is not limited by the
present disclosure.
[0067] FIG. 10 illustrates a schematic top view of another
exemplary display panel consistent with the disclosed embodiments,
and FIG. 11 illustrates an exemplary schematic cross-sectional view
of the display panel in FIG. 10 consistent with the disclosed
embodiments. The similarities between FIGS. 5-6 and FIGS. 10-11 are
not repeated here, while certain differences may be explained.
[0068] As shown in FIGS. 10-11, the display area AA may further
include a plurality of pixel electrodes PI, and the compensation
electrode 21 and the pixel electrodes PI may be disposed at the
same layer. The pixel electrode PI may be configured for realizing
a display function. In one embodiment, the display panel may be a
liquid crystal display (LCD) panel. Through respectively applying
appropriate voltages to the common electrode and the pixel
electrodes in the LCD panel, an electric field may be formed
therebetween for controlling the reorientation of the liquid
crystal molecules, thereby realizing the display function.
[0069] In the manufacturing process of the display panel, the pixel
electrodes PI and the compensation electrode 21 may be
simultaneously formed by patterning the same metal layer, such that
the compensation electrode 21 may be fabricated without introducing
extra film layers, which may reduce the manufacturing process and
the cost of the display panel.
[0070] FIG. 12 illustrates another exemplary schematic
cross-sectional view of the display panel in FIG. 10 consistent
with the disclosed embodiments. The similarities between FIG. 11
and FIG. 12 are not repeated here, while certain differences may be
explained.
[0071] As shown in FIG. 10 and FIG. 12, the compensation electrode
21 and the gate lines GL may be disposed at the same layer. In the
manufacturing process of the display panel, the gate lines GL and
the compensation electrode 21 may be simultaneously formed by
patterning the same metal layer, such that the compensation
electrode 21 may be fabricated without introducing extra film
layers, which may reduce the manufacturing process and the cost of
the display panel.
[0072] It should be noted that, in the above embodiments, the
present disclosure only exemplifies the structure of the film layer
where the compensation electrode is disposed. It is understood that
the compensation electrode may be disposed at other film layers of
the display panel, as long as the compensation electrode is at
least partially overlapped with the winding portion, and
electrically insulated from the winding portion.
[0073] FIG. 13 illustrates an exemplary schematic cross-sectional
view of the display panel in FIG. 2 consistent with the disclosed
embodiments. As shown in FIG. 2 and FIG. 13, the display panel may
include a first substrate 100, a second substrate 200 arranged
opposite to the first substrate 100, and a liquid crystal (LC)
layer 300 disposed between the first substrate 100 and the second
substrate 200. The first substrate 100 may include the plurality of
gate lines GL and the plurality of data lines DL. The display panel
may be an LCD panel, in one embodiment, the first substrate 100 may
be an array substrate, and the second substrate 200 may be a color
film substrate.
[0074] In one embodiment, the first substrate 100 may include an
array layer 110, and the array layer 110 may include a plurality of
thin film transistors ST. Each thin film transistor ST may include
a semiconductor portion T1, a gate electrode T2, a source electrode
T3, and a drain electrode T4. The gate electrode T2 and the gate
lines GL may be disposed at the same layer. The source electrode
T3, the drain electrode T4 and the data lines DL may be disposed at
the same layer. The data line DL and the source electrode T3 may be
electrically connected, and the drain electrode T4 and the pixel
electrode PI may be electrically connected.
[0075] In one embodiment, the color film substrate may comprise a
substrate 001, and a black matrix BM and color filters CF disposed
on the substrate 001.
[0076] The present disclosure further provides a display device,
including any one of the disclosed display panels and a housing for
accommodating the display panel.
[0077] FIG. 14 illustrates a schematic top view of an exemplary
display device 1000 consistent with the disclosed embodiments. As
shown in FIG. 14, the display device 1000 may include a display
panel 1001. The display panel 1001 may be any one of the disclosed
display panels. FIG. 14 shows the display device 1000 may be a
mobile phone, which is for illustrative purposes and is not
intended to limit the scope of the present disclosure. The display
device 1000 may also be any display device with a display function
and/or fingerprint recognition function, such as a laptop, a
television, a tablet, and an in-vehicle display device, etc., which
is not limited by the present discourse. Because the disclosed
display device includes any one of the disclosed display panels,
the disclosed display device may also have the same features as the
disclosed display panel, and details are not described herein
again.
[0078] In one embodiment, as shown in FIG. 14, the display panel
1001 may include a groove R, and the groove R and a first sub-area
101 may be disposed adjacent to each other in a row direction X.
The display device may further include a light sensing element 1002
disposed at the groove R.
[0079] In the disclosed embodiments, the light sensing element 1002
may be disposed at the groove R to detect an optical signal and
convert the optical signal into an electrical signal. For example,
the light sensing element 1002 may include a camera, and an
infrared sensor, etc. The specific structure of the light sensing
element 1002 is not limited by the present discourse.
[0080] In the disclosed embodiments, the display area may have an
irregular shape disposed with the notch, at least one data line may
be desired to be routed from the first sub-area, i.e., the
irregular-shaped data line. A portion of the irregular-shaped data
line where the portion is disposed at the first sub-area may be the
winding portion. The compensation electrode may be disposed at the
first sub-area, and the compensation electrode and the winding
portion may be overlapped to form a coupling capacitance, thereby
increasing the load of the irregular-shaped data line. Compared to
the existing display panel, in the disclosed display panel, the
load difference between the irregular-shaped data line and the
regular data line may be reduced, such that the split-screen of the
display panel may be suppressed, the uniformity of the display
performance may be improved, and the display performance may be
enhanced.
